Metallographic structure: The structure is characterized by austenite type.

A high-alloy steel that can resist corrosion in the air or in chemically corrosive media. Stainless steel has a beautiful surface and good corrosion resistance. It does not need to undergo surface treatment such as plating, but uses the inherent surface properties of stainless steel. It is used in many applications. A kind of steel, usually called stainless steel. High-alloy steels such as 13 chrome steel and 18-8 chrome-nickel steel represent performance.

From a metallographic point of view, because stainless steel contains chromium, a very thin chromium film is formed on the surface. This film isolates the oxygen from the intrusion of the steel and acts as a corrosion resistance. In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 12% chromium. 304 is a versatile stainless steel, which is widely used to make equipment and parts that require good overall performance (corrosion resistance and formability). 304 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard. 304 is equivalent to our country's 0Cr19Ni9 (0Cr18Ni9) stainless steel. 304 contains 17% chromium and 7% nickel. 301 is the most widely used stainless steel and heat-resistant steel. Used in food production equipment, Xitong chemical equipment, nuclear energy, etc. Chemical composition specifications of 304 stainless steel C Si Mn P S Cr Ni (nickel) MoSUS431 ≤0.08 ≤1.00 ≤2.00 ≤0.05 ≤0.03 18.00-20.00 8.25~10.50 -304 is 1Cr17Ni7.

301 (17Cr-7Ni-carbon) material: Compared with 304 steel, the content of Cr and Ni is less, the tensile strength and hardness are increased during cold working, and it is non-magnetic, but it is magnetic after cold working. Uses: trains, aircraft, conveyor belts, vehicles, bolts, springs, screens.
